An IDC survey found that the iPhone 4 antenna issue is sending mixed results. On July 16, 2010, IDC fielded a brief directional survey done in collaboration with the IDG TechPanel that seeked to provide insight into the impact the technical problems with the Apple iPhone 4 will have on the buying behavior of those in the market for a new phone. The survey indicated that 66% of current iPhone owners have been delaying their purchase of the iPhone 4, thus lengthening the normal upgrade cycle associated with the release of a new device. However, the antenna issues do not seem to be impacting the 74% of non-iPhone owners who indicated that they are not delaying their purchase plans.

Earlier this month, Apple had confirmed that the antenna issue was related to the iPhone's 4 software that determines how many signal bars to display. To solve this issue, the company released last week iOS 4.0.1 software update for iPhone 4.
